Performance Analysis of Dynamic Light Weight Cryptographic Algorithm for Message Queuing Telemetry Transport based IoT Communications

This paper presents a novel approach aimed at developing a secure secret key-sharing system optimized for resource-constrained Internet of Things devices. Focusing on the Message Queuing Telemetry Transport protocol, the research endeavours to establish secure communication channels between Internet of Things devices and brokers, thereby enhancing the overall security of Message Queuing Telemetry Transport-based Internet of Things deployments. This research introduces a novel Dynamic Lightweight Authentication for Message Queuing Telemetry Transport mechanism tailored to the unique needs of Internet of Things devices operating under the Message Queuing Telemetry Transport protocol. Dynamic Lightweight Authentication for Message Queuing Telemetry Transport mechanism leverages an innovative lightweight Generalized Feedback Shift Register based Pseudo-Random Number Generator to generate ephemeral keys, ensuring secure communication while addressing the limitations of computational power and energy resources. Through a detailed comparative analysis with existing cryptographic solutions, the Dynamic Lightweight Authentication for Message Queuing Telemetry Transport mechanism demonstrates superior performance in terms of computational overhead, energy consumption, and execution time, while maintaining robust security against common attacks such as Man-in-the-Middle and Denial of Service). he proposed algorithm’s adaptability and scalability are validated using the Cooja simulator, where simulated Internet of Things networks are subjected to various threat scenarios. The results confirm the Dynamic Lightweight Authentication for Message Queuing Telemetry Transport mechanism’s efficacy, showcasing a significant reduction in resource utilization without compromising the strength of the security provided
